Furnace Installation

How Much Space Should I Leave Open Around My Furnace?

Natural gas furnaces need sufficient space and airflow to heat right.

Your furnace can get too hot if it doesn’t have enough space. It also makes it hard for our specialists to accomplish furnace repair.

Routine furnace maintenance is important to keep your unit running trouble-free. An annually serviced furnace may work more efficiently, which could reduce your heating expenses.

Maintenance often helps us notice troubles before they become expensive. This could help reduce future repair costs and potentially prolong the life of your unit.

So how much room should your equipment really have?

How Much Space Does My Furnace Need?

If you’re finishing your basement or enclosing your furnace room, you should take a look at manufacturer directions and Pocatello ordinances for clearance guidelines.

As a general recommendation, your system should be 30 inches away from furnace room walls on all sides. This allows our service technicians to conveniently work on it.

You also need to check the area has ample airflow and ventilation, especially if you have an outdated furnace with a metal flue.

This model of furnace needs combustion air from the adjacent space. If there’s not enough air, hazardous gas fumes and toxic carbon monoxide could back draft into your home.

If your furnace is positioned in a small room with a gas water heater, you may need to install supplemental openings. This could involve a fully louvered door or vents in the walls.

You don’t need to think about airflow and ventilation as much if you have a newer, high-efficiency furnace with PVC piping. Your unit uses one pipe as an exhaust vent and the other to pull in air.

Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as laundry and storage space, you should keep yours free of clutter that could be fire hazards.

This includes:

  • Clotheslines
  • Cleaning or laundry products
  • Gasoline, paint or paint thinner
  • Rags and papers
  • Wood scraps and sawdust
  • Used filters

If you have a cat, place your litter box elsewhere. Cat urine contains ammonia, which could corrode your furnace’s heat exchanger. Plus, the furnace could move the stinky odors all over your home.

You should also frequently vacuum by your furnace to prevent dust from developing.
